Hydroponics is a way of growing plants without soil. Hydroponics, translates from hydro=water and ponos=works. Hydroponics literally means water works. Hydroponic equipment is best suited for indoor gardening or greenhouses. Soilless gardening lets plant take up nutrient faster which means a quicker growing, more compact and more nutritious plant in a smaller space.
Calibration
Calibrating your pH meter is very important to it's health. Keep your meter calibrated for long term use.
What would you say if I was to tell you that an organism smaller than
the tip of a pin can be all the difference between a high-yielding
crop, or disease, infestation, and flop? It's true! And let me explain
just how this can be.
In nature soil contains a wide range of bacteria and mycorrhizae.
Most people know what bacteria are, but mycorrhizae deserves an
explaination. Mycorrhiza is a form of fungus that forms a network with
the roots of many plant species. These mycorrhizae come in two main
forms: endomycorrhizae and ectomycorrhizae. Ectomycorrhizae form on the
outside of roots while endomycorrhizae actually penetrate the roots of
plants. Both types grow in a network of threads called "hyphae". As
these hyphae grow through the medium, be it soil or otherwise, they increase the surface area of the roots thus allowing the plant to which they have formed a symbiotic
relationship with to more easily locate and absorb water and nutrients.
In this sense, you can think of mycorrhizae as extra roots. But wait,
that's not all!
Both beneficial bacteria and mycorrhizae excrete enzymes.
Enzymes are catalysts that speed up the pace of a chemical reaction.
The reaction these enzymes are catalyzing are the breakdown of the
nutrients in your soil or other medium into smaller, more usable forms
that the plant can take up through its roots and use for energy to
increase overall health and yield. So, not only are mycorrhizae
increasing the surface area of the roots so plants can more easily
access water and nutrients, they are actually helping to "pre-digest"
the nutrients in conjunction with beneficial bacteria. You can think of
them as teeth for you plant!
Further,
beneficial bacteria and mycorrhizae give your plants an immune boost!
They do this by displacing and competing with harmful bacteria (such as
Pythium,
the cause of root rot). Its the same reason there has been a craze for
probiotics such as those found in yogurt. If you have a strong
population of good bacteria in your stomach you are less likely to get
sick. The same goes for plants but instead of the beneficial bacteria
living internally, they live externally in the growing medium.
One final point - beneficial bacteria and mycorrhizae are helpful in
hydroponics as well as soil, especially when using organic fertilizers
that contain nutrients that are not readily available. Just be sure not
to subject them to chlorine or chloramines
(found in municipal water supplies) as these can kill your populations
that you have spent valuable time and money cultivating!
